SPECIFICATION forming part of Letters Patent No. 608,979, dated August 9, 1898. Application filed November 17,1896. Renewed June 3, 1898. Serial No, 682,503. (No model.)

To ctZZ whom it may concern:

Be it known that I,JOHN'GOOD,OE New York, (Far Rockaway,) in the county of Queens and State of New York, have invented a new and useful Improvement in Machinery for Preparing Fibrous Materials for Spinning, of which the following is a specification.

This invention relates to that class'of machinery for preparing fibrous materials in which the materials are subjected to a combing operation by means of pins which are car ried by endless chains or tables.

The principal object of the improvement is to obtain a machine into which the raw fibers of sisal and other long-fibered plants may be introduced in the condition in which they are taken from the bale and by which such fibers are so operated upon as to be delivered from itin the form of slivers ready for spinning, thereby accomplishing at a single operation by one machine what has heretofore required several operations performed successively by as many diiferent machines.

To enable others skilled in the art to make and use my invention, I will proceed first to describe it in detail, with reference to the accompanying drawings, and afterward to point out its novelty in claims.

Figures 1 and 2 are opposite side views of a machine embodying my invention. Fig. 3 is a longitudinal vertical sectional view of the same. Fig. 4 represents a transverse vertical section in the line 4: 4 of Figs. 1, 2, and 3. Fig. 5 is a dia ram corresponding with a portion of Fig. 3, but on a larger scale, illustrating the operation of the principal features of the invention. J

Similar letters of reference designate corresponding parts in all the figures.

A is the framing of the machine, on or in which are the bearings for the shafts a b and a b, which carry the wheels 0 d and 0 cl, on which run the two sets of endless chains B and B, which carry the two sets of bars 6 e, in which are the twotrains of gill-pins ff, by which the fibers are to be operated upon. These shafts, chains, wheels, bars, and pins may all or any of them be of any known or suitable construction, such as is common to spreading and drawing machines, and are representedof ordinary construction. The

several shafts and the two sets of chains are soarranged that the two tables or platforms formed by the bars and pins in their upper runs are in line with each other, as is common in spreading-machines. The shafts of the several chains are so geared that while the two trains of pins move in the samedirection, as indicated by arrows in Figs. 3 and 5, the second train travels much faster than the first train f as compared with the relative speeds of the first and second trains of pins in the spreading-machines in which such two trains of pins are used. In the example represented the speed of the second train f is about twenty times that of the first train. This difierence of speed may, however, be varied according to circumstances.

' The driving of the chain-shafts may be effected in any suitable manner. Those of the first set are represented as driven from those of the second set, which are represented as driven by a gear 9 on the shaft 9 of one of a set of drawing or delivery rollers O 0' G which are arranged at the forward end of the upper run of the chains B to take the fibers therefrom. The whole train of gearing for driving the two sets of chains is represented in Fig.1 and will now be described. The gear 9 above mentioned engages with a gear h on the shaft b of the chains B and so drives the said chains, which themselves drive their shaft a. On the latter shaft is a gear 2', which engages with and drives a pinion j, turning loosely on a fixed stud on the framing A, which pinion also engages with and drives a gear is, turning on a fixed stud Z. To this gear 70 is fastened a chain-wheel m,

which, through an endless chain m, drives a second chain-wheel 'n on a fixed stud p. This stud p-carries a small spur-gear o, whichengages witihand drives a largerspur-gear 19*, turning on a fizged stud q and havingfast to it a smaller spur-gear T, which engages with and drives a larger spur-gear s on thefshaft 5 b of the first chains B and so drives the said chains.

On the sides of the framing are ways G,

which extend from points forward of the chain-wheels b of the first chains B backward some distance beyond the rear of the said chains, the said ways being parallel both ver too tically and laterally with the table or platform constituted by the straight upper run of the said chains and their bars 6 and pins f. On these ways G run a carriage D, in which is mounted the axle E of a reel or lanternwheel E, which extends across the chains B. The height of this reel above the ways and the spacing of its rungs t are such that the rungs will enter between the rows of pins in the bars of the upper run ,of the chains B and press upon a bed of fiber imposed on the said bars, and that as the carriage D is moved back and forth on the ways the reel may be caused to rotate by the contact of its rungs with the said pins. The axle E of the reel" is so mounted in its bearings in the carriage that the reel may be capable of a sufficient rise and fall to accommodate itself to the thickness of the bed of fibers on the bars 6. Behind the reel E there is mounted on the carriage D a feed-board F, the front end of which is just high enough to clear the points of the pins f. The mechanism for producing the backward-and-forward movement of. the carriage to roll the reel over the pins f, which is fully represented in Fig. 2, will now be described.

His a right and left hand threaded endless screw the shaft or core of which is fitted to turn freely, but confined lengthwise in fixed bearings u on the frame A. This screw, Which is parallel with the ways, is fitted with a switch-nut I, which by the continuous rotation of the screw in one direction is caused to run back and forth upon the right and left hand threads. As such screws and nuts are common in spinning-machines I have not thought it necessary to represent the nutswitch in detail. The said nut I is connected with the carriage D by a rod J.

The screw H is represented as furnished with a pulley 1;, through which it may have a rotary motion imparted to it by a belt to. The speed at which the carriage and the feedboard and reel thereon are caused to move back and forth will be verymuch slower than that of the second chains B and their train of pins f, yet several times faster than that of the first chains B and their train of pins f. The range of movement of the carriage is such as to carry the reel forward to about a position nearly over the forward end of the upper run of the chains B, as shown in full outline in Fig. 5, and backward to a position some distance beyond the chain, as shown in dotted outline in the same figure.

Over the interval between the chains B B there are arranged transversely to the chains one or more bars L, of which there are two in the example represented, each being armed with a downwardly-projecting row of gillpins f These bars have their ends secured in two blocks x, which are fitted to slide up and down in fixed guides at upon the machine-framing. The said blocks have connected with them the yokes M of two cams M on a rotary shaft N, which extends across the machine and is supported in suitable bearings in or on the sides of the framing. The said shaft is furnished with a spur-gear y, Figs. 1 and 4, which engages with and receives motion from the gear 70, hereinbefore referred to as one of the train for driving the chains B. The rotary motion of the shaft N thus obtained produces through the cams M such a downward-and-upward reciprocating motion of the pin-bars L as to cause the pins f to penetrate and be withdrawn from a bed or layer of fibers passing from the chain B to that B and to cause the said bars to beat down lightly the said fibers, so as to keep them from rising above the points of the pins f and f.

The operation of the invention is as follows: The several parts of the machine having imparted to them the movements which have been hereinbefore explained an attendant takes in his hand a bunch of raw fiberssuch, for example, as the bunches in which the raw hemp comes in the bale to marketand while the feed-carriage D with the feedboard F and reel E are moving forward he wit-h his hands places the fibers lengthwise along the board and spreads them to some extent across the same, and just as the carriage D arrives in the forward position, in which it is shown in full outline in Fig. 5, he pushes the bunch forward under the rearmost rungs of the reel, which as the return movement of the carriage takes place turns in the direction of the arrow shown upon it in Fig. 5 and so draws the fibers from the feed-board and deposits them downward upon and between the pins f of the first train. This operation is repeated during every movement of the carriage backward, and the successive bunches are thus superposed in several layers upon the pins fand bars e; but as the chains B with the said bars and pins are continuously moving forward at a speed much slower than that of the carriage the several layers are superposed each some distance behind the next layer below, and so the ends of the fibers of the several layers lap or break joint with each other, as indicated at 6 7 8 9 in Fig. 5. The first chains and theirpins f carry forward the so-disposed layers of fiber to the pins f of the second train, which, moving so much faster than those f of the first train gradually comb and draw out the fibers from the several layers coming from the pins f until they become practically one layer, which becomes more and more attenuated, until it reaches the drawing-rollers O O 0 very thinly spread and with the ends of the several single fibers of which it is composed very thoroughly distributed. During this operation the reel E both in its forward and backward movements keeps the several layers of fibers pressed down, so that they are prevented from rising above the pinsf, while the portions of the fibers between the two chains are repeatedly beaten down lightly by the bars L and so prevented from rising above the pins ff, while the pins f* penetrating the said portions of the fibers tend to separate them laterally and also hold them against the combing operations of the pins f. The thin layer of fibers taken by the drawing-rollers O O G from the second train of pins f and passing over a tapered delivery-board P with raised sides, such as is common in spreading and drawing machines, is contracted laterally into the form of a sliver, which is delivered by delivery-rollers Q, such as are commonly placed in front of said boards, to any suitable receptacle or to any suitable device for further operation.

What I claim as my invention is 1. The combination of two tables arranged one before the other and each comprising bars armed with pins, means for moving the said tables both in one direction but at different speeds, a feed-board arranged over the slowernioving table, and means for moving the said feed-board back and forth over the latter table for depositing fibers downward upon the pins of the slower-moving table, substantially as herein described.

2. The combination of two tables arranged one before the other and each comprising bars armed with pins, means for moving the said tables both in one direction but at different speeds, afiber-feeding carriage and means for moving the said carriage back and forth over the slower-moving table toward and from the faster-moving table at a speed greater than that of the slower-moving table but less than that of the faster-moving table, substantially as herein described.

3. The combination of two tables arranged one before the other and each comprising bars armed with pins, means for moving the said tables both in one direction but at difierent speeds, a beating-bar arranged over the space between said tables, and means for giving a reciprocating motion to said bar for the purpose of pressing down the fibers on their way from one of said tables to the other, substantially as herein described.

l. The combination of two tables arranged one before the other and each comprising bars armed with pins, means for moving the said tables both in one direction but at difierent speeds, a fiber-feeding carriage, means forv moving the said carriage back and forth over the slower-moving table toward and from the faster-moving table at a speed greater than that of the slower-moving. table but less than that of the faster-moving table, and a beatingbar arranged and operating between the said tables, substantially as herein described.
